EFFECT OF EVAPORATIVE CONDENSER BY CAPILLARY ACTION ON VCR SYSTEM USING R600a AND CuO NANO MIXED WITH POE OIL AS LUBRICANT

Abstract

The concept of effect of evaporative condenser on the coefficient of performance of vapor compression system mainly carried out to improve the coefficient of performance of system by using R600a and 0.5%V of CuOnano mixed with Polyolester oil as lubricant. To improve the COP, it is required that decreases the compressor work and refrigerating effect should increases. The aim of increasing the COP of refrigeration system by using evaporative condenser instead of the air cooled condenser. In the evaporative condenser (wick from the basin wet the condenser tubes by capillary action) is used to decrease the condensing temperature which results in decrease the energy consumption by compressor and then coefficient of performance (COP) will increased. The cloth should be super absorbent fabric, which is absorbs high amount of water. Wick suck the water by capillary action from the basin and wet the condenser tubes, then the condenser rejects the heat by evaporation which results low condensing temperature compared to air cooled condenser. In additional fan or blower fixed at the end of the condenser, then heat transfer rate increases due to forced convection. Hence COP should improve and also getting better performance compared with earlier observations.
